Operation timing
The operation timing of a speed change by the override function is shown below.

(1) When running, speed change starts from the position where override ratio was changed.
(2) When override ratio is set to "0", just as when speed is changed to "0", a deceleration stop is performed and
"[St.1049] Speed change "0" accepting flag (R: M30272+n/Q: M2240+n)" turns ON.
(3) Operation is restarted by changing the override ratio from "0".
(4) Even when the override ratio has been changed at the start, acceleration/deceleration is performed with the
speed including the override ratio.
